MRL Traction Elevator Architecture

MRL - Machine Room-Less

Smart space, silent ride, lower energy bills — the entire drive system inside the hoistway.

MRL – MACHINE ROOM-LESS

Smart Space, Silent Ride

Brisk MRL elevators place the entire drive system inside the hoistway, freeing up valuable rooftop space and cutting construction costs. Ideal for modern buildings where rooftop space or height restrictions matter.

No Machine Room Gearless PMSM Up to 50% Energy Savings
How it works

Inside the MRL System

Compact, gearless, and controlled by a VVVF drive — engineered for smooth vertical travel.

A compact gearless Permanent Magnet Synchronous Motor (PMSM) is mounted on the guide rails at the top of the shaft. It drives the car and counterweight through steel wire ropes or coated flat belts. A VVVF (Variable Voltage Variable Frequency) drivecontrols speed smoothly from start to stop. The controller sits in a slim cabinet at the top landing door frame or in the shaft wall, so no separate machine room is needed.

Key features

What Makes MRL Different

No machine room

Saves 10–15 sq m of building space and reduces civil work.

Gearless PMSM traction

No gearbox oil, low noise and up to 40–50% energy savings versus geared machines.

VVVF control

Smooth acceleration, accurate levelling (±5 mm) and lower starting current.

Microprocessor controller

Collective selective operation, fault diagnostics and service logs.

ARD (Automatic Rescue Device)

Moves the car to the nearest floor and opens doors during a power failure.

Automatic sliding doors

Centre or side opening, with full-height infrared light curtain.

Custom cabins

Stainless steel (hairline / mirror / etched), glass, laminate or powder-coated finishes, LED lighting and false ceiling options.

Optional regenerative drive

Feeds braking energy back to the building supply.
